Quinine Sulfate

Quinine Sulfate

Quinine Sulfate is used for the treatment of malaria. This is used alone or with other medications to treat the condition. Malaria is a mosquito-borne disease caused by a parasite. The parasite is transmitted to humans through the bites of infected mosquitoes. People with this disease frequently experience chills, fever, and flu-like illness. If you are traveling to locations where malaria is common, take steps to prevent mosquito bites by wearing protective clothing. Depending on the area you are visiting and your individual risk factors for the infection. You may also take preventive medications before, during and after your trip. Malaria infection is generally characterized by the following signs and symptoms:

  • Headache
  • Fever
  • Chills
  • Muscle pain and fatigue
  • Nausea and vomiting
  • Cough
  • Chest or abdominal pain
  • Sweating

Malaria parasites can enter the body through these mosquito bites. These parasites live in body tissues such as red blood cells. Once these enter your body, they travel to your liver where they multiply. They invade your red blood cells which are important cells in your blood that carry oxygen. The parasites get inside them, lay their eggs, and multiply until the red blood cell bursts. This releases more parasites into your bloodstream. As they attack more of your healthy red blood cells, this infection can make you feel very sick.

This medication sometimes may also be used to treat recurrent night-time leg cramps. It can take up to 4 weeks of taking Quinine Sulfate before an improvement in the condition is seen. You should keep a sleep and cramp diary for a few weeks before you start taking Quinine Sulfate and continue this while you are taking it. It is to help you monitor whether the medicine is helping. If your cramps don’t seem to have improved after 4 weeks of taking this drug then it should be stopped.

Quinine Sulfate is a type of medicine called an antimalarial. This kills the malaria parasites during their development stage in the liver and inside red blood cells. This is supplied for oral use as capsules. Each capsule is available in the dosage form of 324 mg. The Food and Drug Administration (FDA) has already approved this prescription.

How does Quinine Sulfate work?

Quinine Sulfate attacks the parasites once they have entered the red blood cells. It kills the parasites and prevents them from multiplying further. Malaria is a potentially fatal disease that is caused by several types of single-celled parasites known as Plasmodium. Plasmodium is carried by mosquitoes and injected into the bloodstream during a bite from an infected mosquito. Once in the blood, the parasites travel to the liver where they multiply. The parasites are then released back into the bloodstream where they invade the red blood cells and multiply again. An actual attack of malaria develops when the red blood cells burst, releasing a mass of parasites into the bloodstream. The attacks do not begin until a sufficient number of blood cells have been infected with parasites.
